92133-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92133-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,3 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 92133-52:
(7*9)+(6*2)+(5*1)+(4*3)+(3*3)+(2*5)+(1*2)=113
113 % 10 = 3
So 92133-52-3 is a valid CAS Registry Number.
